b5-38 PID User Unit Display
Scaling
(01FE)
The drive uses this parameter and b5-39 [PID Setpoint Display Digits] together.
When b5-20 = 3 [PID Unit Selection = User Units], the drive applies user-set PID setpoint and display units to
these parameters and monitors:
• b5-19 [PID Setpoint Value]
• b5-58 [PID Setpoint2]
• b5-59 [PID Setpoint3]
• b5-60 [PID Setpoint4]
• U5-01 [PID Feedback]
• U5-04 [PID Setpoint]
• U5-99 [PID Setpoint Command]

No.
Name
(Hex.)
b5-40 Frequency Reference
Monitor @PID
(017F)
0 : U1-01 Includes PID Output
Monitor U1-01 shows the frequency reference that was increased or decreased by the PID output.
1 : U1-01 Excludes PID Output
Monitor U1-01 shows the actual frequency reference.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the length of time that the PID feedback signal must be more than the level set in b5-36 [PID
Feedback High Detection Lvl] to cause Excessive PID Feedback [FbH].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the value that the drive sets or shows as the PID setpoint when at the maximum output
frequency.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the number of digits to set and show the PID setpoint.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the contents for monitor U1-01 [Frequency Reference] in PID control.
